ISL88001IE22Z-T

Supervisors Overview

The ISL88001IE22Z-T is a low-power voltage supervisor IC manufactured by Renesas Electronics Corporation. It monitors a single input voltage and provides an active-low, push-pull reset output when the supply drops below or exceeds specific thresholds. The device operates within a supply voltage range of 1.8 V to 5.5 V and features a fixed reset delay time of 190 ms. It is housed in a compact SC-70-3 surface-mount package and is designed for applications requiring precise power management with minimal quiescent current consumption.

Supervisors Feature Summary

• Provides reliable system reset via active-low push-pull output upon detecting under-voltage or over-voltage conditions
• Features low quiescent current consumption suitable for battery-powered and energy-efficient designs
• Includes a fixed internal reset delay timer to ensure stable power-up sequencing

Supervisors Applications

• Portable electronic devices requiring efficient power monitoring
• Embedded systems needing precise voltage supervision
• Industrial control circuits with strict power integrity requirements

Supervisors Procurement Notes

Verify the exact suffix 'IE22Z-T' against official Renesas documentation to confirm the specific threshold voltage and tape-and-reel packaging configuration. Ensure compatibility with existing PCB footprints for the SC-70-3 package. Check for any recent product change notices regarding manufacturing locations or material compositions before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with a fixed 190 ms delay is required. The SC-70-3 package offers space efficiency for dense layouts. Consider the 1.8 V to 5.5 V operating range to ensure compatibility with the target system's power rails. Verify that the active-low output polarity matches the downstream logic requirements.

Supervisors Part Context

This part belongs to the ISL88001 series of voltage supervisors from Renesas. The series includes variants with different threshold voltages and output configurations. The ISL88001 family is designed for general-purpose power management tasks in consumer, industrial, and communication equipment where reliable reset generation is critical for system stability.

Supervisors Replacement Considerations

Consult official Renesas cross-reference lists for direct substitutes. Ensure any replacement maintains the SC-70-3 footprint, 190 ms delay, and compatible threshold voltage specifications.
